The Million Dollar Equations - with Tom Crawford

In the year 2000 it was announced that seven of the biggest unsolved problems in mathematics would each be given a $1million prize. Only one has been solved. Watch the Q&A:    • Tom Crawford - Million Dollar Equations - Q&A   Subscribe for regular science videos: http://bit.ly/RiSubscRibe The seven million dollar equations are: the Riemann hypothesis, Navier-Stokes equations, P vs NP, the Poincare conjecture, Yang-Mills mass-gap hypothesis, the Birch and Swinnerton-Dyer conjecture, and the Hodge conjecture. In this talk, explains four of them.
